The bank admitted no wrongdoing in agreeing the 31 October settlement, but Florida attorney general Pam Bondi called it a “substantial recovery on behalf of [the state’s] retirement fund”.
The settlement provides full compensation for the state’s past foreign currency trades and ensures complete transparency on the pricing of future trades, according to the attorney general.
It also compensates the Florida Retirement System Trust Fund for investments made through BNY Mellon’s securities lending programme, on behalf of the state, in medium-terms notes issued by Sigma Finance, which defaulted on certain notes in September 2008 before going into receivership.
“We worked hard to achieve this substantial recovery on behalf of Florida’s retirement fund,” said Bondi in a statement.
BNY Mellon became the Florida Retirement System Trust Fund’s custodian in July 2005, signing a securities lending agreement at the same time.
A whistleblower originally brought the case against BNY Mellon, but the State of Florida joined in 2011.
A BNY Mellon spokesperson said: "We are gratified that the Florida attorney general is withdrawing her lawsuit and that we have resolved issues related to the State Board of Administration’s securities lending programme. We’re also pleased to reach an agreement with the State Board of Administration that allows us to continue our longstanding relationship."
"We have always viewed these issues as commercial matters and have taken a pragmatic approach to resolving them directly with our clients."
Sigma Finance’s legacy has already cost BNY Mellon millions of dollars.
In its Q2 2012 results, the bank said it had put aside up to $280 million to settle in part a complaint from workers’ compensation insurance company CompSource Oklahoma.
It filed the complaint over losses connected with the investment of securities lending collateral in Sigma Finance.
